TILE CEILING.

SPECIFICATION forming part of Letters Patent No. 386,376, dated July 17,18

Application filed February 25, 1888.

T0 aZZ whom it may concern:

Be it known that l, Janns H. BRIGHT, of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Tile Ceilings; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Fignre l is a sectional elevation of a coil.- ing, showing my improvements. detail side elevation of a joist and tile.

This invention relates to improvements in tile ceilings; and it has for its objects to improve the construction of the tiles and supporting devices therefor, whereby the floor beam will be protected from fire, as will be readily understood from the following descrip tion, when taken in connection with the annexed drawings, and particularly specified in the appended claims.

Referring to the drawings by letter, A dcs ignates a floorbeam provided at bottom with opposite outstanding flanges, (t (1.

B designates a tile of greater width than the flanged portion 01' beam A, and formed with a central loi'igitudinal groove or channel, I), in its upper surface, which is nearly as wide as the flanged portion of the tloorbeam, beneath .which the tile is secured. In the edges of tile B are made the longitudinal grooves O O, forming double lips c c on the edges of the tile, and the bottom of the tile is formed with dovetailed grooves or mortar binds D, as shown. Tiles B are secured beneath and sup ported by floonbeains A by means of clips E E, which are bent to fit the upper surface of flanges of the floor-beams, and are also bent around the upper lip, c, of the tile B, as shown at e, and thereby suspend the latter on the floor-beam. There are two or more of these clips used with every tile, one being preferably placed at each corner of the tile.

F indicates skew-tiles, which are placed on each side of joists A, and support the usual intermediate arch and key tiles. The tiles F are formed with shoulders f to fit over the flanges a, by which they are supported, and they also serve to keep the clips E E in posi- Fig. 2 is a- Scrial No. 265,247. (No model.)

tion, so that they cannot slip outward and disengage from tiles B, as is evident. Tiles F are also provided with a groove, G, and hp 9, coinciding with the grooves G and lower lip, c, of tile B. The lower face of tile F has also a number of inortar-biud grooves, H.

When the parts are in position as shown, it will be seen that an air-space is left beneath the floor-beams and tile B by the channel bin the latter. The plaster, when applied to the surface of tiles B and F, will press up into the grooves O and G between the tiles and form a tight joint between the latter.

The tiles B protect the floor-beams from injury by ti re, owing to their width, and the tiles F, when in proper position on the floorbeams and the space between the grooves G and 0 filled with mortar, not only hold the clips E in position, but serve as additional supports and braces for the tiles B by reason of the tight mortar joint, thus adding additional strength and security to the structure.

Having described my invention, I claim- 1. The herein-described tile B, having a longitudinal channel, I), in its upper surface and longitudinal grooves (l C in its edges, substantially as and for the purpose described.

2. The combination of the double-flanged joist A and the tile B, having longitudinal channel I) in its upper surface and grooves C C in its side edges, with the bent clips E E, engaging the flanges of the girder, and in the grooves of tile B, suspending the latter from the girder, and the shouldered skewtiles holding said clips in position, all constructed and arranged substantially as and for the purpose described.

3. The combination ofjoist A, clip E, and tiles B, having grooves O in their side edges, with the skew-tiles F, having shouldersf, and grooves O, coinciding with grooves G of the tiles B when in position, as and for the purpose specified.

In testimony that Iclaini the foregoing as my own I affix my signature in presence of two witnesses.
